Application filed August 10, 1914. Serial No. 856,091.

This invention relates to car vestibule trapl doors and has for its object a particularly simple and etlicient means by which the passengers clothes are prevented from fouling on the operating member for the lock of the trap door; and it consists in the. combinations and constructions hereinafter set forth and claimed. w

In describing this invention, reference is had to the accompanying drawings. in which like ch aracters designate corresponding parts in all the views.

Figure l isa planA view of this trap door lock, the contiguous part of a car vestibule being also shown. Fig. 2is a section, partly in-elevation, on the plane of line .le-A. Fig. l, the contiguous part of the trap door being also shown.

l designates the trap door which, as will be understood by-those skilled inthe art, is hinged to the vestibule in position to .move into a horizontal position to cover the ve"- tibule steps and into a vertical position to uncover the steps, the movement from closed to open position being effected by a spring, and the door being usually held from opening by a lock mounted on the platform end sill 2.

3 designates the movable operating meinber ot' the lock, said member being depressiblc or movable downwardly to operate a level' 4 which coacts with a pivoted latch 5 coaeting with the trap door 1 the lever 4 andv lat'h 5 being mounted within a suitable housing 6 suitably secured to the end sill Q. The mechanism ot the lock forms uo part of this invention. A

The operating member is 'formed with a head at its upper end7 and the edge oi the head is covered by a. stationary shield usually carried by an upright walletl the vestibule called the vestibule finish.v rlhe head is located entirely at one side ot the operativi member which usually a ve"- tieal roilgor shank, and here shown. the head is an arm l evlemlii'igj laterally lrom the rod or shank aud having: its fares routiguous to the shank, flush with the faces of the shank so that where the head joins the shank there are no projections on which passengers clothes might catch. The arm 7 terminates close to the upright wall or tinish 8 of the vestibule.

9 is the shield secured to the finish 8 in any suitable manner, as by screws, the shield projecting far enough from the finish to cover the end edge portion ot the arm 7, and the upper surface thereof being inclined downwardly and outwardly from the finish 8 as at l0 to facilitate the sliding of the trainmans foot along the shield in order to deflect it onto the head Y, so that the trainnians foot will not lodge cn the shield.

The working' of the operating member is the same as heretoi'fone7 ihat is, when it is desired to open the trap door l, the'trainman depresses the member 2l with his toot to operaie the latch 5 to release the door l, but heretofore the upper end of the operat ingmember has been an unprotected projec tion on which passengers clothes were liable to catch. By my invention, the head is iu the iorm of a laterally extending' arm 7, the endpot' which is located under the shield 9 so that it is impossible tor passengers clothes to hook over the head 7, and at the same time, the head is readily accessible to the trainman as the shield does not interfere with the operation ot' the member El.

lVhat l claim is l. A railway car vestibule trap door lock comprising a movable operating,y member carried by a portion ot the car and includ.- ing a projecting portioiulocatcd above the platform surface, and a stationary shield cova-:ringau edge portion ot the operating' member to prevent passengers clothes trom catching ou the, operating;` member, substantially asv and for the purpose d.;"cribed.

A. railway car vestibule trap door lochY comprisiug, au operating` member carried by a portion ot the ear and including;` a verlical shaulv and' a laterally evtending head at its upper end terminating .near a. verte-ai wall oi.: the vestibule, the sidey and end sur- 'taces of the head near the shank of the oporating member beine' flush with the shank, substantially as aud for the purpose specilied.

3. A railway ear vr" .ibule trap door lo( comprising an operating; member carried the platform. and having a. laterallycxtend- ,j.,

ing head, and a stationary shield covering the outer end of said head to prevent passengers clothes from fouling on the head,

substantially as and for the purpose set. forth.

Y laterally extending head at the upper end of the shank, thehead extendinglaterally on one side of the shank and terminating near aside Wall of the vestibule, and a shield carried by the side Wall in position to cover the outer end of said arm, substantially as and lfor the purpose described.

5. A railway car vestibule trapndoor lock' comprising an operating member carried by a portion of the car and including a vertical shank and a laterally extending head at its upper end terminating near a vertical -Wall of the vestibule, the side andend sur# faces of the head near the shank of the operating` member being flush with the shank,

and a shield carried by said Wall of vthe car in position to cover the outer end of said arm, substantially1 as and for the purpose specified.

6. A railway carvestibule trap door lock: comprising a depressible operating member on the 'platform end sill,said member hav ing a laterally extending'head lat its upper end and terminating near the side Wall of the vestibule, and a shield carried by the side Wall imposition to cover the outer end of said arm, the shield havingI an inclined upper face which inclines downwardly and outivardlyfrom said Wall, substantially as and for the purpose set forth.'

' 7. A railway car vestibule trap door lock comprising a movable operating member including a head located entirely at one side of the operating member, and a static-nary shield covering the extremity4 of the head,

substantially as and for the purpose described.

in testimony whereof, l have hereunto signed my name in the presence of twol attesting Witnesses, at Syracuse, inl the county of Onondaga, inthe State or' New York, this 4Zi'th day of July, 1914i.
